Module: Coatepec::Spec::Result

Defined in:
lib/coatepec/spec/result.rb

Overview

Turns a finished RSpec child process's exit status, captured stdout/stderr (each capped at MAX_OUTPUT_BYTES), and RSpec's own JSON formatter output into the flat result hash rails_spec_run returns.

Constant Summary collapse

MAX_OUTPUT_BYTES = 
256 * 1024

Class Method Summary collapse

Class Method Details

.base(pid, status, stdout_result, stderr_result) ⇒ Object

rubocop:disable Metrics/MethodLength -- one flat hash literal mapping Process::Status/captured-output fields to the result payload's own field names; splitting it would scatter that 1:1 mapping across methods for no readability gain.
